JeremyAnsel.ColorQuant is a C# implementation of the Xiaolin Wu's Color Quantizer (v. 2). For a given 32-bit RGB or ARGB image, it will produce a 8-bit palletized image.

C Implementation of Xiaolin Wu's Color Quantizer (v. 2) (see Graphics Gems volume II, pages 126-133) : http://www.ece.mcmaster.ca/~xwu/cq.c.

Algorithm: Greedy orthogonal bipartition of RGB space for variance minimization aided by inclusion-exclusion tricks. For speed no nearest neighbor search is done. Slightly better performance can be expected by more sophisticated but more expensive versions.

Usage

For image with RGB data:

var quantizer = new WuColorQuantizer();
ColorQuantizerResult result = quantizer.Quantize(image, colorCount);

For image with ARGB data:

var quantizer = new WuAlphaColorQuantizer();
ColorQuantizerResult result = quantizer.Quantize(image, colorCount);

ColorQuantizerResult contains a palette and the result bytes.
